Morphology

conk + out

The verb 'conk' (to stop functioning or to knock someone out) combined with the particle 'out' (indicating complete cessation or unconsciousness) makes the general idea of stopping/going unconscious reasonably inferable from the parts. However, because 'conk' is somewhat low-frequency and polysemous and the specific extension to both mechanical failure and falling asleep is not fully predictable without exposure, the expression is only partially transparent.

Etymology

Conk out may come from the old slang conk for the head. If someone was hit and was knocked out, they 'conked out'. People then used the same idea for machines: when a machine suddenly stops it is as if it was knocked out, so conk out means 'to stop working' or 'to fall asleep'.
